The Pediatric Balance Scale (PBS) is a modified Berg's Balance Scale developed as a balance measure for school-aged children with mild to moderate motor impairments. The purpose of this study was to determine the inter-examiner reliability of the Korean version of PBS when applied to children with developmental delays. In this study, PBS was administrated to a total of 79 children with developmental delays (17 with global developmental delay, 31 with cerebral palsy, and 31 with mental retardation) in the Seoul Community Rehabilitation Center. Two pediatric trained physical therapists with longer than 13 year of clinical experience scored the children's performance blind, while replaying videotaped data. The inter-examiner reliability was statistically determined by intraclass correlation coefficients (ICCs). The results of this study revealed that the Korean version of PBS seems to have high inter-examiner reliability when applied to children with movement disorders such as global developmental delay (ICC=.96) and cerebral palsy (ICC=.97); however, it has relatively lower inter-examiner reliability (ICC=.78) for children with developmental delay secondary to mental retardation. therefore, the results support that the Korean version of the PBS could be a useful clinical measurement to assess the balance skills for children with developmental delay who have an adequate level of cognition to enable them to fol1ow the verbal instructions to complete the test.

This study was undertaken to evaluate the status of intestinal protozoan infections in the children of specific groups. A total number of 441(male 250; female 191) consisting of 224 children of national feeble minded children institute, 59 Han-Bit blindness students, 158 children of local mental retardation children institute(Kang-Dong Ku) of specific groups were examined. The method employed was formalin-ether sedimentation technique with Lugol's iodine stain. The results were as follows: 1) The positive rates for any kinds of protozoan cysts were 13.8%(72 positives out of 441 samples) with sexual difference of 14.0% in male and 12.6% in female. 2) In the institute differences of positive rates of protozoan cysts were 15.2% in national feeble minded children institute, 16.9% in Han-Bit blindness school, and local mental retardation children institute(Kang-Dong Ku). 3) Cysts of Entamoeba coli were recovered in 8.6% and cysts of pathogenic amoeba, Entamoeba histolytica were found in 1.4%. Cysts of Endolimax nana (3.4%). Giardia lamblia (2.9%) were found in this study. 4) The degree of multiple infections of protozoan cysts were; single infection 81.4%, double infection 16.9% and quadriple infection 1.7% respectively.

This study is for the segmentation and volume calculation of the white matter and gray matter from brain MRI. In general, the volume of white and gray matter is reduced by contraction of each components in the case of mental retardation which are Alzheimer's disease and Down's syndrome. As results, it is useful for diagnostic and early detection for various mental retardation through the tracing of variation for its volume from the brain MRI. But, until now, it was very difficult to calculate the partial volume of each components existing in some thickness, because MR image was represented by single gray value after scanning by MR scanner. Accordingly, new segmentation algorithm proposed in this paper is to calculate the partial volume of the white and gray matter existing in some thickness through the analysis of the blurred gray value, and is to determine the threshold for segmentation of white and gray matter, and is to calculate the volume of each segmented component. And finally, proposed algorithm was applied the models which was created manually, and then acquired results was compared with that of original model.

Background: We aimed to assess the dose needed to achieve the propofol effect-site concentration using target-controlled infusion in intellectually disabled patients and to detail the most effective method for achieving a safe level of consciousness without hemodynamic changes as well as detail any resulting adverse effects. Methods: We performed a retrospective review of sedation service records of 138 intellectually disabled patients (51, mental retardation; 36, autism; 30, brain lesion, 12 genetic diseases, 9 dementia) aged over 15 years and weighing over 30 kg. These patients had received propofol via target-controlled infusion in the special care dental clinic of Seoul National University Dental Hospital from May 2008 to September 2018 for restorative treatment (112), minor surgery (13), prosthodontics (7), periodontics treatment (5), and implant (1). Results: For all groups, the duration of dental treatments was $43{\pm}18$ minutes, total sedation time was $73{\pm}23$ minutes, and total BIS values was $57{\pm}12$. The propofol maintenance dosage values for each group were: mental retardation, $3{\pm}0.5(2-4){\mu}g/ml$; autism, $3.1{\pm}0.7(2-5){\mu}g/ml;$; brain lesion, $2.8{\pm}0.7(1.5-5){\mu}g/ml;$; genetic disease, $2.9{\pm}0.9(1-4){\mu}g/ml;$ and dementia $2.3{\pm}0.7(1-3.4){\mu}g/ml;$. Conclusions: The dementia group needed a lower dosage to reach a safe, effective propofol effect-site concentration than the other groups. Since there were no complications, deep sedation is a great alternative to general anesthesia for dental treatment of intellectually disabled patients.

Medication is widely accepted as an effective method to reduce the problem of attention deficit, hyperactivity, impulsivity, resistance and violence of ADHD children. However, it does not provide us with the solution on the conflicting routinized behavioral patterns to gain a high level of self-control and acceptable behavior. As a way of replacing medication, this study applies the social skills training program for ADHD children and measures the level of improvement of social skills and the change of the behavioral patterns. The experiment is carried out on 16 children ranged from 6 to 13 years of age for 10 weeks. The patients are divided into three groups：a pure ADHD group, an ADHD group with conduct disorder, an ADHD group with mental retardation and other symptoms. The change of symptoms and the change of social skills are measured by the Child Behavior Checklist(CBCL), the ADD-H Comprehensive Teacher’s Rating Scale(ACTeRS) and the Social Skills Rating Scale(SSRS), and finally Mastson Evaluation of Social Skills for Youth(MESSY). Wilcoxon signed ranks test is used to evaluate the effect of the treatment, and Kruskal-Wallis test is also used to measure the change after the treatment in each of the three groups. In the ADHD group with conduct disorder, the examination of the effect of the treatment shows a significant reduction of violence in the area of behavior(p<.05), and a significant difference of activity and social skills in the area of social competent(p<.001). In the ADHD group with mental retardation and other symptoms, a significant rise of social skills is found in the area of social skills evaluation (p<.05). However, there is no significant difference of effect by the treatment among the three groups. In addition, the current examination shows that the social skills training program does not make a statistically significant contribution to the social skills of the ADHD children. On the other hand, the training helps some children, when it is suitable for the characteristics and accompanying symptoms of the children：it reduces the level of violence in the ADHD group with conduct disorder, and it raises the social skills in the ADHD group with mental retardation. In other words, the social skills training program will reduce the conduct disorder and helps peer relation for ADHD children.

The purpose of this study is to investigate the parental marital relationships and the parent-child relationships of child psychiatric parents and its control group. This study was carried out two questionnaire instruments ; The marital satisfaction inventory(MSI) and the dyadic adjustment scale(DAS). The subjects are parents of the child psychiatric patients. A matched control group and parents of child psychiatric parents in Seoul area which were collected from July 1987 to September 1987, and classified into five subgroups : 1 Psychiatric disorder 2) Neurotic disorder 3) Tic disorder 4) Autistic disorder 5) Mental retardation. The results are as following ; 1) M.S.I scale scores of parents of patients group are lower than that of control group. 2) D.A.S scale score of parents of patients group is significantly lower than that of the control group(P<0.01). 3) The global distress scale(GDS) of the M.S.I. was most positively correlated with affective communication(AFC) and problem-sloving communication(PSC). 4) Female shoed more modern concept of role identification than male but tend to have heavier role assignment especially in child rearing practices which could be characterized by maternal domination. 5) Affective communication and sexual relationship between married couple and child rearing practices are influenced by their own family history of distress. 6) The marital global distress scale(GDS) score was highest in the parents of psychosis, the next in the parents of neurosis, autism, mental retardation, and tic disorder in descending order of severity. 7) The dyadic maladjustment score was highest in the parents of psychosis, the next in the parents of neurosis, tic, autism and mental retardation in descending order of severity. 8) Conflict in child rearing and parenting problems were particularly prominent in parents of the tic patients, and their marital relationship was not significantly disturbed. The above finding suggested that couple adjustment and marital dissatisfaction were closely related with child rearing problems and the children's disorder. So marital dissatisfaction and marital maladjustment seem to play a significant role in the genesis of psychosis and neurosis not much in autism and mental retardation.

The relationship between mercury level of hair and mental retardation was investigated. The 297 subjects with mental retardation were drawn from two schools providing special educational services, one, consisted of children living in an orphan home, another, children with parents. The 117 centre] subjects were drawn from whom had got average or above average academic achivement in a regular elementary school. Hair sample were taken from the nape of the neck and the mercury analysis was carried out on an atomic absorption spectrophotometer(IL 551). There was no relationship between mercury contents and age, and there was a statistically significant difference in mercury contents between male and female in the mentally retarded children living with parents. Children in the retarded group had significantly higher mercury contents compared with control group except the female group with parents. Also, the mercury levels in the retarded group living in an orphan home were significantly higher than that of the retarded group with parents. The concomitant diseases were Down's syndrome, epilepsy, cerebral palsy and autism. There were statistically significant differences in hair mercury levels in the cases of accompanying Down's syndrome and cerebral palsy in male and Down's syndrome and autism in female compared with the control group of the same sex. The most accompanying handicap was speech disturbance(40.7%) and the others were crippled, emotional disturbance etc. The percentages of double handicap were 66.7% among 6 persons exceeding 6ppm of their hair mercury contents. 10.4% among $3{\sim}6$ ppm and 15.7% among the group of 3ppm or less. The findings of this study suggest that the more opportunities of exposure to mercury in mentally retarded children may have occurred, so it can not be excluded the possibility of mercury as a contributing factor to mental retardation. Therefore, the causal relationship between mercury levels and mental retardation should be established through the examinations about their living environments, dietary pattern, eating habit etc.

Purpose : Parents' genetic information plays an important role in their children's genetic expression. Human chromosome has 23-paternal chromosomes and 23-maternal chromosomes. Parental chromosomal translocation can induce clinical problems in their children because of imbalance in genetic information. We intent to analyze the cytogenentic and clinical features about children with maternal balanced translocation between chromosome 15 and 18. Methods : We detected by one family's FISH study of chromosome 15. We have evaluated children born to clinically normal parents about peripheral bood analysis, endocrine, metabolic, radiologic study, electroencephalogram and social & intelligence scale. and We analysis their clinical manifestation by hospital records. Results : Patient's father and elder sister are normal clinically and genetically. Her mother's chromosome show balanced translocation, 46, XX, t(15;18)(p11.2;p11.3). One child has 46, XX, der(18) t(15;18)(p11.2;p11.3), mental retardation, growth retardation, speech & social developmental delay, recurrent infection and mild mitochondria dysfunction. Her young brother has 46, XY, der(15) t(15;18) (p11.2;p11.3), mental retardation, aggressive behavior, obesity and speech developmental delay. Conclusion : In this study we observed the children with developmental delay, dysmorphic facial features, mental retardation, growth retardation associated with growth hormone deficiency and aggressive behavior due to unbalanced translocation between chromosome 15 and 18.

In pseudohypoparathyroidism as reported by Albright in 1942, the parathyroid gland can normally synthesize and secrete parathyroid hormone(PTH). Pseudohypoparathyroidism has a similar biochemical finding with hypoparathyroidisms like hypocalcemia and hyperphosphatemia due to target tissue resistance to PTH. Administered PTH does not raise the serum levels of calcium and urinary phosphate. PTH activates G-protein in peripheral tissue and adenylate cyclase through a second messenger, cAMP. Pseudohypoparathyroidism produces hyperphosphatemia and hypocalcemia because of the resistance to PTH in peripheral tissue due to a defect of G-protein, although it releases PTH normally. According to the mechanism of resistance, pseudohypoparathyroidism is classified into types : Ia, Ib, Ic and psedopseudohypoparathyroism. Type Ia is accompanied by congenital growth retardation and abnormal bony development that shows mental retardation, obesity, low height, round face, short metacarpal bone and metatarsal bone, ectopic calcification, etc. We report a case of pseudohypoparathyroidism in a premature who shows hypocalcemia, hyperphosphatemia, elevation of serum PTH and 24 hr urinary basal c-AMP in biochemical tests without Albright's hereditary osteodystrophy at physical examination, accompanied by a spontaneous fracture in the femur.
